Hello, I don't know anything about your 'search', but this might be useful.
My Great Grandmother kept a boarding house for stage people in Liverpool. We have photographs of some of her boarders who became friends of the family, being photographed at my father's and his twin's christening.
I know their names, Dickie and Poppy Douglas. I therefore searched censuses 1901 and before, and found them in various parts of the country.
So do a general search, not putting down any place or country.
I know that is easier with people who had more unusual names - Jones etc is too difficult.
Sincerely, Rachel Bowen
